A simple hatching egg design.

The base and the top part are printed separately. I used supports for the bottom of the parts in order to avoid issues with overhangs and improve adhesion to the build plate. If you want the egg to stand upright by itself, just don't remove the supports of the base part.

I have uploaded a screenshot of my support setting but you may need to tweak them according to you printer.

Please note that the bird which can be seen on the photo is not a part of this design. You can put inside anything you want :)

You will need to rotate the models on the build plate prior to starting the print. Sorry for that :)
